Cuoco and Cook announced their engagement last December in an Instagram video. The two were first linked in 2016.

\"Well after nearly two years I finally got up the courage to ask her to marry me. This is the best night of my life and I think the video shows it is the best night for Kaley as well....\" Cook wrote in the caption.

This will be the second marriage for Cuoco, who split from tennis player Ryan Sweeting in 2015.
